I bought the box of Jawzrsize products and found that the green one was best resistance for me. After about 3 months the product split at the seam on one side. I tried to use the blue one but when I put the mouthpiece parts into the device it would not stay in and kept falling out. I tried twice and followed the directions exactly, but both times it would not stay in. The product is a good idea but the quality I received was poor. Jawzrsize reached out to me and sent a new replacement box. First class customer service! Product is working great. They truly stand behind their products!!
